基于椭圆曲线完全自组织Ad hoc网络密钥管理方案

Ad hoc Networks Key Management Scheme Based on Elliptic Curve Completely Self-Organization

该文针对目前Ad hoc网络密钥管理方案存在计算量大,可信中心难以确定以及密钥更新周期大小难以确定的问题,提出一种基于ECC完全自组织Ad hoc密钥管理方案。该方案为解决计算量大而采用EEC代替RSA,以完全自组织方式解决可信中心的瓶颈,通过使用双重密钥更新机制克服定期更新大小难以确定等问题。本方案具有计算代价小,安全可靠,扩展性好等优点,适合大规模Ad hoc网络。

According to the current key management scheme exist large computation,trusted centre and key update cycle size is difficult to determine problems,we proposed a scheme that based on ECC fully self-organization Ad hoc key management in this paper.The sckeme use ECC instead of RSA for large computation;in order to solve trusted centre,we use fully self-organization ;By using a double key update to overcome the regular updating cycle size problem.Computational cost of this program has a small compuation safe,reliabilityand good scalability for large-scale Ad hoc network.
